DETAILED DESCRIPTION OF THE DRAWINGS

The numerous innovative teachings of the present application will be described with particular reference to the presently preferred exemplary embodiments. However, it should be understood that this class of embodiments provides only a few examples of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily delimit any of the various claimed inventions. Moreover, some statements may apply to some inventive features but not to others.

FIG. 1 shows an IPTV system 100 including a client facing tier 102, an application tier 104, an acquisition tier 106, and an operations and management tier 108. Each tier 102, 104, 106, and 108 is coupled to one or both of a private network 110 and a public network 112. For example, the client-facing tier 102 can be coupled to the private network 110, while the application tier 104 can be coupled to the private network 110 and to the public network 112 such as the Internet. The acquisition tier 106 can also be coupled to the private network 110 and to the public network 112. Moreover, the operations and management tier 108 can be coupled to the public network 112.

The various tiers 102, 104, 106, and 108 communicate with each other via the private network 110 and the public network 112. For instance, the client-facing tier 102 can communicate with the application tier 104 and the acquisition tier 106 via the private network 110. The application tier 104 can also communicate with the acquisition tier 106 via the private network 110. Further, the application tier 104 can communicate with the acquisition tier 106 and the operations and management tier 108 via the public network 112. Moreover, the acquisition tier 106 can communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, elements of the application tier 104 can communicate directly with the client-facing tier 102.

The client-facing tier 102 can communicate with user equipment via a private access network 166, such as an Internet Protocol Television (IPTV) network. In an illustrative embodiment, modems such as a first modem 114 and a second modem 122 can be coupled to the private access network 166. The client-facing tier 102 can communicate with a first representative set-top box device 116 via the first modem 114 and with a second representative set-top box device 124 via the second modem 122. The client-facing tier 102 can communicate with a large number of set-top boxes over a wide geographic area, such as a regional area, a metropolitan area, a viewing area, or any other suitable geographic area that can be supported by networking the client-facing tier 102 to numerous set-top box devices. In one embodiment, the client-facing tier 102 can be coupled to the modems 114 and 122 via fiber optic cables. Alternatively, the modems 114 and 122 can be digital subscriber line (DSL) modems that are coupled to one or more network nodes via twisted pairs, and the client-facing tier 102 can be coupled to the network nodes via fiber-optic cables. Each set-top box device 116 and 124 can process data received from the private access network 166 via an IPTV software platform such as Microsoft® TV IPTV Edition.

The first set-top box device 116 can be coupled to a first display device 118, such as a first television monitor, and the second set-top box device 124 can be coupled to a second display device 126, such as a second television monitor. Moreover, the first set-top box device 116 can communicate with a first remote control 120, and the second set-top box device 124 can communicate with a second remote control 128. In an exemplary, non-limiting embodiment, each set-top box device 116 and 124 can receive data or video from the client-facing tier 102 via the private access network 166 and render or display the data or video at the display device 118 or 126 to which it is coupled. The set-top box devices 116 and 124 thus may include tuners that receive and decode television programming information for transmission to the display devices 118 and 126. Further, the set-top box devices 116 and 124 can include a set-top box processor 170 and a set-top box memory device 172 that is accessible to the set-top box processor. In a particular embodiment, the set-top box devices 116 and 124 can also communicate commands received from the remote controls 120 and 128 back to the client-facing tier 102 via the private access network 166.

In an illustrative embodiment, the client-facing tier 102 can include a client-facing tier (CFT) switch 130 that manages communication between the client-facing tier 102 and the private access network 166 and between the client-facing tier 102 and the private network 110. As shown, the CFT switch 130 is coupled to one or more data servers 132 that store data transmitted in response to user requests, such as video-on-demand material. The CFT switch 130 can also be coupled to a terminal server 134 that provides terminal devices, such as a game application server and other devices with a common connection point to the private network 110. In a particular embodiment, the CFT switch 130 can also be coupled to a video-on-demand (VOD) server 136.

The application tier 104 can communicate with both the private network 110 and the public network 112. In this embodiment, the application tier 104 can include a first application tier (APP) switch 138 and a second APP switch 140. In a particular embodiment, the first APP switch 138 can be coupled to the second APP switch 140. The first APP switch 138 can be coupled to an application server 142 and to an operation systems and support/billing systems and support (OSS/BSS) gateway 144. The application server 142 provides applications to the set-top box devices 116 and 124 via the private access network 166, so the set-top box devices 116 and 124 can provide functions such as display, messaging, processing of IPTV data and VOD material. In a particular embodiment, the OSS/BSS gateway 144 includes OSS data, as well as BSS data.

The second APP switch 140 can be coupled to a domain controller 146 that provides web access, for example, to users via the public network 112. The second APP switch 140 can be coupled to a subscriber and system store 148 that includes account information, such as account information that is associated with users who access the system 100 via the private network 110 or the public network 112. In a particular embodiment, the application tier 104 can also include a client gateway 150 that communicates data directly to the client-facing tier 102. In this embodiment, the client gateway 150 can be coupled directly to the CFT switch 130. The client gateway 150 can provide user access to the private network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116 and 124 can access the system via the private access network 166 using information received from the client gateway 150. The private access network 166 provides security for the private network 110. User devices can access the client gateway 150 via the private access network 166, and the client gateway 150 can allow such devices to access the private network 110 once the devices are authenticated or verified. Similarly, the client gateway 150 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices, from accessing the private network 110 by denying access to these devices beyond the private access network 166.

For example, when the set-top box device 116 accesses the system 100 via the private access network 166, the client gateway 150 can verify subscriber information by communicating with the subscriber and system store 148 via the private network 110, the first APP switch 138 and the second APP switch 140. Further, the client gateway 150 can verify billing information and status by communicating with the OSS/BSS gateway 144 via the private network 110 and the first APP switch 138. The OSS/BSS gateway 144 can transmit a query across the first APP switch 138, to the second APP switch 140, and the second APP switch 140 can communicate the query across the public network 112 to the OSS/BSS server 164. After the client gateway 150 confirms subscriber and/or billing information, the client gateway 150 can allow the first set-top box device 116 access to IPTV content and VOD content. If the client gateway 150 cannot verify subscriber information for the first set-top box device 116, such as because it is connected to a different twisted pair, the client gateway 150 can deny transmissions to and from the first set-top box device 116 beyond the private access network 166.

The acquisition tier 106 includes an acquisition tier (AQT) switch 152 that communicates with the private network 110. The AQT switch 152 can also communicate with the operations and management tier 108 via the public network 112. In a particular embodiment, the AQT switch 152 can be coupled to a live acquisition server 154 that receives television content, for example, from a broadcast service 156. Further, the AQT switch can be coupled to a video-on-demand importer server 158 that stores television content received at the acquisition tier 106 and communicate the stored content to the client-facing tier 102 via the private network 110.

The operations and management tier 108 can include an operations and management tier (OMT) switch 160 that conducts communication between the operations and management tier 108 and the public network 112. In the illustrated embodiment, the OMT switch 160 is coupled to a TV2 server 162. Additionally, the OMT switch 160 can be coupled to an OSS/BSS server 164 and to a simple network management protocol (SNMP) monitor 166 that monitors network devices. In a particular embodiment, the OMT switch 160 can communicate with the AQT switch 152 via the public network 112.

In a particular embodiment during operation of the IPTV system, the live acquisition server 154 can acquire television content from the broadcast service 156. The live acquisition server 154 in turn can transmit the television content to the AQT switch 152 and the AQT switch can transmit the television content to the CFT switch 130 via the private network 110. Further, the television content can be encoded at the D-servers 132, and the CFT switch 130 can communicate the television content to the modems 114 and 122 via the private access network 166. The set-top box devices 116 and 124 can receive the television content from the modems 114 and 122, decode the television content, and transmit the content to the display devices 118 and 126 according to commands from the remote control devices 120 and 128.

Additionally, at the acquisition tier 106, the VOD importer server 158 can receive content from one or more VOD sources outside the IPTV system 100, such as movie studios and programmers of non-live content. The VOD importer server 158 can transmit the VOD content to the AQT switch 152, and the AQT switch 152 in turn can communicate the material to the CFT switch 130 via the private network 110. The VOD content can be stored at one or more servers, such as the VOD server 136.

When a user issues a request for VOD content to the set-top box device 116 or 124, the request can be transmitted over the private access network 166 to the VOD server 136 via the CFT switch 130. Upon receiving such a request, the VOD server 136 can retrieve requested VOD content and transmit the content to the set-top box device 116 or 124 across the private access network 166 via the CFT switch 130. In an illustrative embodiment, the live acquisition server 154 can transmit the television content to the AQT switch 152, and the AQT switch 152 in turn can transmit the television content to the OMT switch 160 via the public network 112. In this embodiment, the OMT switch 160 can transmit the television content to the TV2 server 162 for display to users accessing the user interface at the TV2 server. For example, a user can access the TV2 server 162 using a personal computer (PC) 168 coupled to the public network 112.

The domain controller 146 communicates with the public network 112 via the second APP switch 140. Additionally, the domain controller 146 can communicate via the public network 112 with the PC 168. For example, the domain controller 146 can display a web portal via the public network 112 and allow users to access the web portal using the PC 168. Further, in an illustrative embodiment, the domain controller 146 can communicate with at least one wireless network access point 178 over a data network 176. In this embodiment, each wireless network access point 178 can communicate with user wireless devices such as a cellular telephone 184.

In a particular embodiment, the set-top box devices can include a set-top box computer program 174 that is embedded within the set-top box memory device 172. The set-top box computer program 174 can contain instructions to receive and execute at least one user television viewing preference that a user has entered by accessing an Internet user account via the domain controller 146. For example, the user can use the PC 168 to access a web portal maintained by the domain controller 146 via the Internet. The domain controller 146 can query the subscriber and system store 148 via the private network 110 for account information associated with the user. In a particular embodiment, the account information can associate the user's Internet account with the second set-top box device 124. For instance, in an illustrative embodiment, the account information can relate the user's account to the second set-top box device 124 by associating the user account with an IP address of the second set-top box device, with data relating to one or more twisted pairs connected with the second set-top box device, with data related to one or more fiber optic cables connected with the second set-top box device, with an alphanumeric identifier of the second set-top box device, with any other data that is suitable for associating second set-top box device with a user account, or with any combination of these.

FIG. 2 shows one example embodiment of a television distribution system or network 200, using IPTV technology in this example but not limited thereto, adapted to provide, among other things, the live television content features of the disclosed subject matter. The network 200 may include a super hub office (SHO) 210 for acquisition and encoding of video content, one or more video hub offices (VHO) 220 in each demographic market area (DMA), one or more intermediate offices (IO) 230, one or more central offices (CO) 240 located in each metropolitan area, and subscribers 250, who may be located in single or multiple dwelling units. In one example embodiment, the network 200 may be connected through a plurality of high speed communication links 260 using physical transport layers such as fiber, cable, twisted pair, air, or other media.

In one example embodiment of the IPTV video delivery system, the SHO 210 distributes content to one or more VHOs 220 which may be spread across a wide geographic territory, such as an entire country. The SHO 210 may, for example, be in a central location for acquisition and aggregation of national-level broadcast television (or linear) programming. A redundant SHO 210 may be provided for backup in case of failure. The SHO 210 may also provide the central point of live television content acquisition and insertion into the IPTV network. Linear programming may be received at the SHO 210 via satellite and processed for delivery to the VHO 220. Live television content may be received from various sources and processed/encoded to codec and bit-rate requirements for the communication network for transmission to the VHO 220 over the high speed communication links. The VHOs 220 are the video distribution points within each DMA or geographic region.

FIG. 3 shows an exemplary network architecture 300 between the CO 240 and customer premises equipment (CPE) 320 of the subscriber 250 shown in FIG. 2. A serving area interface (SAI) or video ready access device (VRAD) 310 may be connected to the CO 240. SAI 310 may, for example, be located in a weather-proof enclosure proximate the subscriber 250 premises, and may include fiber-to-the-node (FTTN) equipment, such as a digital subscriber line access multiplexer (DSLAM). FTTN equipment may also be located in the CO 240. The customer premises equipment (CPE) 320 includes, for example, a network interface device (not shown) and a residential gateway (RG) 330, with a built-in very-high-bit-rate digital subscriber loop (VDSL) modem or optical network termination (ONT). In either case the RG 330 may be connected to the rest of the home set-top box devices 116 and 124 via an internal network such as an Ethernet. The set-top box devices 116 and 124 each have an associated remote control device 120 and 128 which provides data entry to the set-top box devices to control the IPTV selections from the IPTV data streams.

FIG. 4 shows a portion of the IPTV system 100 including an installation request server 402, a test server 404, and an IPTV server 406. In an embodiment, the installation request server 402, the test server 404, and the IPTV server 406 are all preferably located within an IPTV provider network, such as the private network 110. The installation request server 402 is in communication with the test server 404, which in turn is in communication with the IPTV server 406. In one embodiment, the test server 404 is also in communication with a Federal Communications Commission (FCC) server 408 via the public network 112.

The installation request server 402 can receive a new user installation request indicating a location of a new user installation and the type of service requested. For example, the new user installation request can indicate that a user connected to one of the RGs 330 has requested to receive IPTV service from the IPTV system 100 of FIG. 1. Alternatively, the new user installation request may be a proposal by the IPTV service provider to install IPTV cabling from the VRAD 310 to each of the RGs 330 and/or customer premises within a new neighborhood. In one embodiment, the IPTV cable can preferably be a twisted pair wire between the VRAD 310 and the RG 330. In another embodiment, the IPTV cable can be a fiber optic cable connecting the VRAD 310 to the RG 330. The installation request server 402 can forward the new user installation request to the test server 404. After receiving the new user installation request, the test server 404 can determine if any potential interferences to the IPTV signal exist within a geographical location associated with the user connected to the RG 330 and the VRAD 310.

While determining any potential interferences, the test server 404 can retrieve information about an area surrounding the geographical location of the new user installation from the IPTV server 406. The information can include a geographical location of the each of the VRADs 310, a geographical location of each of the RGs 330 and/or customer premises, a geographical location of projected IPTV cable routes from the VRADs to each of the RGs and/or customer premises, and the like. The test server 404 can access a database of the FCC server 408 to retrieve geographical locations of amplitude modulation (AM) broadcasting facilities and amateur radio operators, which can be potential interferences for an IPTV signal transmitted over the IPTV cables from the VRADs 310 to the RGs 330 and/or the customer premises. The test server 404 can also access the FCC server 408 to retrieve power levels and/or transmission power ratings for the signals broadcast from the AM broadcasting facility and/or the amateur radio operator. Upon retrieving the information from the IPTV server 406 and the FCC server 408, the test server 404 can plot and/or map graphical representations of the VRADs 310, the RGs 330, the IPTV cable routes 502, the AM broadcasting facilities, and the amateur radio operators at different locations on a graphical user interface (GUI) representing a large area surrounding the location associated with the new user installation, as shown in FIG. 5.

FIG. 5 shows an exemplary screen shot 500 of a plot of sources of potential IPTV signal interference. The exemplary screen shot 500 includes potential IPTV cable routes 502 to connect the VRADs 310 with the RGs 330, an AM broadcasting facility 504, amateur radio operators 506, a navigation panel 508, and a search toolbar 510. In an embodiment, the screen shot 500 can be a GUI associated with the test server 404 such that a user can enter a location into the search tool bar 510 and can view graphical representations of the VRADs 310, the RGs 330, the IPTV cable routes 502, the AM broadcasting facilities 504, and amateur radio operators 506 located within the specific location. For example, the test server 404 can use the location, such as a zip code, entered into the search toolbar 510 to search and retrieve the information associated with a large geographical location around the area from the IPTV server 406 and the FCC server 408. The test server 404 can then display graphical representations of the large geographical location as shown in the exemplary screen shot 500.

When the different geographical representations are plotted and/or mapped, the test server 404 can determine the distances between the AM broadcasting facilities 504 and the VRADs 310, the RGs and/or customer premises 330, and the projected IPTV cable routes 502. The test server 404 can also determine the distances between the amateur radio operators 506 and the VRADs 310, the RGs and/or customer premises 330, and the projected IPTV cables routes 502. Each of the distances can be stored in a database of the test server 404 for later reference.

In an embodiment, the user can vary the GUI display of the large geographical location. For example, if the user wants to view a specific location of the area entered into the search toolbar 510, the user can utilize the navigation panel 508 to pan across the area, zoom in or out in on a specific location, and the like. Thus, the GUI displayed by the test server 404 can provide the user with a graphical representation of the locations and distances between the VRADs 310, the RGs and/or customer premises 330, the projected IPTV cables routes 502, the AM broadcasting facilities 504, and the amateur radio operators 506. The test server 404 can retrieve the power levels and/or transmission power ratings for the signals broadcast from each AM broadcasting facility 504 and/or amateur radio operator 506. For example, the power level for the signals can range from two hundred Watts to fifty Kilowatts depending on the AM broadcasting facility 504. The amateur radio operator 506 can have power levels that range from two hundred Watts to one and one half Kilowatts, but with the use of gain antennas and effects of local conditions the power level experienced by the IPTV system can be higher.

An amount potential interference caused by the AM broadcasting facility 504 and/or the amateur radio operator 506 can depend on a combination of the power levels of the broadcast signals from the AM broadcasting facility and/or the amateur radio operator, and the distance the AM broadcasting facility and/or the amateur radio operator are from the VRAD 310, the RG 330, and/or the IPTV cable route 502. Thus, a threshold distance for determining potential interference can vary depending on the power level of the broadcast signal from the AM broadcasting facility 504 and the amateur radio operator 506. For example, if the AM broadcasting facility 504 operates with a power level of five Kilowatts for the broadcast signal, the threshold distance can be ten kilometers before the AM broadcasting facility causes any potential interference with an IPTV signal. However, if the amateur radio operator 506 transmits at a power level of one and one-half kilowatts for the broadcast signal, the threshold distance for the amateur radio operator can be one kilometer.

Thus, the test server 404 can determine whether there might be potential interferences with an IPTV signal traveling over the ITPV cable route 502 from the VRAD 310 to the RG 330 based on whether the AM broadcasting facility 504 and/or the amateur radio operator 506 are within the threshold distance as determined in response to the power level of the broadcast signal from either the AM broadcasting facility and/or the amateur radio operator. The sources of potential interference can cause problems with the IPTV signal, Voice over Internet Protocol (VoIP) telephone signal, and/or IP data signals transmitted over the IPTV cable route 502. The possible problems caused by the potential interference can include an inability for the RG 330 to synchronize with the VRAD 310, pixelization and/or loss of IPTV video signal, dropout or complete loss of the VoIP telephone signal, intermediate and/or continuous disruption of data sent over the IP data line of the IPTV cable route 502, and the like.

Upon identifying at least one potential interference of the IPTV signal, the test server 404 can select different mitigation strategies to limit the effect of the potential interference. The mitigation strategies can include repairing the IPTV cable route 502, connecting bridge taps in the VRAD 310, twisting the IPTV cables located in the VRAD, installing filters at the RGs and/or customer premises 330, and the like. The filters can be designed to block signals within the frequency ranges of the broadcast signals from the AM broadcasting facility 504 and the amateur radio operator 506. The test server 404 can assign these mitigation strategies as a support ticket for the technicians responsible for completing the new user installation request.

FIGS. 6-8 show a flow diagram of a method 600 for determining multiple mitigation strategies to limit potential interferences of an IPTV signal. At block 602, a new installation request is received at a server in an IPTV system. A first geographical location of a customer premises associated with the new user installation request is retrieved at block 604. The first geographical location of the customer premises can be retrieved from a database of the IPTV service provider. At block 606, a second geographical location of an amplitude modulation (AM) broadcasting facility is retrieved. The second geographical location of the AM broadcasting facility can be retrieved from a database of the federal communication commission (FCC). A graphical representation of the customer premises is plotted at the first geographical location and a graphical representation of the AM broadcasting facility is plotted at the second geographical location at block 608. The plot of the graphical representations of the customer premises and the AM broadcasting facility can be on a GUI representing a large area surrounding the first and second geographical locations.

At block 610, a first distance between the first geographical location and the second geographical location is determined. A first signal transmission power rating for the AM broadcasting facility can be retrieved at block 612. The first signal transmission power rating can be retrieved from the database of the FCC. At block 614, the first distance is compared to a first threshold distance that is based on the signal transmission power rating for the AM broadcasting facility. For example, the first threshold distance can be a larger or smaller distance based on the signal transmission power rating for the AM broadcasting facility being lesser or greater. At block 616, a first mitigation strategy to limit a first potential interference of the AM broadcasting facility on an IPTV signal provided to the first geographical location is determined when the first distance is less than the first threshold distance.

At block 618, a third geographical location of an amateur radio operator is retrieved. A graphical representation of the amateur radio operator is plotted at the third geographical location at block 620. The plot of the graphical representation of the amateur radio operator can be on the GUI as described above. At block 622, a second distance is determined between the first geographical location and the third geographical location. A second signal transmission power rating for the amateur radio operator is retrieved at block 624. At block 626, the second distance is compared to a second threshold distance that is based on the second signal transmission power rating for the amateur radio operator. At block 628, a second mitigation strategy to limit a second potential interference of the amateur radio operator on the IPTV signal provided to the first geographical location is determined when the second distance is less than the second threshold distance.

At block 630, a fourth geographical location of a video ready access device (VRAD) associated with the new user installation request is retrieved. A graphical representation of the VRAD is plotted at the fourth geographical location of at block 632. The plot of the graphical representation of the VRAD can be on the GUI as described above. At block 634, a third distance is determined between the second geographical location and the fourth geographical location. The third distance is compared to a third threshold distance that is based on the first signal transmission power rating for the AM broadcasting facility at block 636. At block 638, a third mitigation strategy to limit a third potential interference of the AM broadcasting facility on the IPTV signal provided from the fourth geographical location to the first geographical location is determined when the third distance is less than the third threshold distance.

At block 640, a projected IPTV cable route is determined between the fourth location and the first location. A graphical representation of the projected IPTV cable route is plotted at block 642. The plot of the graphical representation of the projected IPTV cable route can be on the GUI as described above.
